摘　　要：采用激光二极管端面泵浦Nd∶YVO4晶体和声光调Q技术,获得1.34μm脉冲激光,利用基质材料YVO4晶体的拉曼频移效应,将1.34μm激光转变为1.52μm(人眼安全激光),获得最大平均输出功率930mW,相应光-光转换效率为3.4%,激光器输出的最短单脉冲宽度为15.6ns,最高峰值功率为3.02kW.The 1.34 μm pulsed radiation was generated with an acousto-optical Q-switched Nd： YVO4 laser endpumped by laser-diode-array. Simultaneously, it was converted into 1.52μm radiation through Raman frequencyshift effect by YVO4 crystal. The maximum average output power at 1.52μm was obtained to be 930 mW, with the corresponding optical conversion efficiency of 3.4% Additionally, the shortest pulse width and the highest peak power were obtained to be 15.6 ns and 3.02 kW, respectively.
